spatial-framework-for-hadoop

The Spatial Framework for Hadoop allows developers and data scientists to use the Hadoop data processing system for spatial data analysis.

For tools and samples that use this framework, head over to GIS Tools for Hadoop.

What's New

• Huge improvements in performance for Hive ST_Geometry UDFs.
• For example, the Hive sample with ~175 million points now takes 4 minutes, down from 75 minutes, on a 20 node cluster.

Features

• JSON Utilities - Utilities for interacting with JSON exported from ArcGIS
• Javadoc
• Hive Spatial - User-Defined Functions and SerDes for spatial analysis in Hive
• UDF Documentation
• JSON Serde

Getting Started

Maven

Build as you would any other Mavenized repository. All dependencies are pulled automatically.

Ant

Ant build files are also available

At the root level of this repository, you can build a single jar with everything in the framework using Apache Ant. Alternatively, you can build a jar at the root level of each framework component (i.e., hive\build.xml).

The build files use Maven Ant Tasks for dependency management. You will need the jar in a place Ant can find it (i.e., ~/.ant/lib/maven-ant-tasks-2.1.3.jar).

Dependencies

• Esri Geometry API for Java - Java geometry library for spatial data processing.

Requirements

• Hive 0.10.0 and above (or Hive 0.9.0 patched with HIVE-2736)
• Workflows calling MapReduce jobs require the location of the custom job to be run.
• Custom MapReduce jobs that use the Esri Geometry API require that the developer has authored the job, (referencing the com.esri.geometry.* classes), and deployed the job Jar file to the Hadoop system, prior to the ArcGIS user submitting the workflow file.

• ArcGIS Geodata Resource Center
